I wonder who uses such antique versions anyway (current is 7.0, 2.6 is not listed in release notes but seems to be from 2015).
Or are there two different versioning schemes?

Haha, https://gist.github.com/lqez/3944436 11 years ago. Maybe it's just 🦖 old.

What happened here? I can't find ngx.null in the docs

I used nil at first, but this didn't work. I've noticed that other functions in this module use ngx.null instead.

Lua's nil value in an array-like Lua table can make "holes" in the array, which is troublesome for many things, like with the # operator.
When being returned directly as a single value, we need to distinguish a Lua nil value that indicates a low-level error (like network communication failures or timeout) and a valid redis-land null value.
For unit testing, you can swap your lua or luajit command with the resty command (which is provided by OpenResty under <openresty-prefix>/bin/. See
https://github.com/openresty/resty-cli
for the documentation.
